Return 0/1 if a unique value is found in another column.

Hello!

I want to do a test to see if a ID appears in another table that is a subest of the data. 

So for example:

3   1   0

4   2   0

5   3   1

     5   1

     6   0

I feel like there might be a easy soultion to do, but just can't find anything online! 

Thanks!
